The four pie charts illustrate the percentage of vehicles—cars, trucks, and SUVs—sold in the United States in 1980, 1990, 2000, and 2010. The unit is measured in percent.
In 1980, cars accounted for the vast majority of the vehicle sales at 80%. This figure declined by 75% in 1990, while trucks made up 15%, and SUVs were only 5%.
By 2000, the trend became more balanced, as cars dropped further to 50%, with trucks and SUVs rising 20% and 30%, respectively. By 2010, cars were recapping the market, but SUVs became as popular as cars, representing 40% of sales compared to 45% for cars, while trucks only captured 15% of the total proportion.
Overall, the data highlights a clear shift from car dominance in 1980 to a diversified market by 2010. Furthermore, cars consistently made up the largest proportion of sales throughout the period, although their share gradually decreased, while the market share for trucks and SUVs rose significantly.
